To get an object of PrintWriter in Java, we use the getWriter() method of the HttpServletResponse class.
Option A) HttpSession - This option is incorrect because the getWriter() method is not a method of the HttpSession class.
Option B) HttpServletResponse - This option is correct. The getWriter() method is a method of the HttpServletResponse class, which is used to send a response to the client.
Option C) HttpServletRequest - This option is incorrect because the getWriter() method is not a method of the HttpServletRequest class.
Option D) None - This option is incorrect because the correct answer is option B, HttpServletResponse.
The correct answer is B) HttpServletResponse. This option is correct because the getWriter() method is used to obtain a PrintWriter object to write the response to the client using the HttpServletResponse class.
